Dual License with MIT and Apache 2.0

[ParkMyCar]

Switching this library to a dual license model of MIT and Apache 2.0 to follow other open source crates in the Rust ecosystem would be nice.

Since MIT licensed software can be relicensed as Apache 2.0, you can just do that.

The "MIT OR Apache-2.0" model is liked by many open source products, because the user of the library can choose to use MIT license (effectively: do what you want, but don't sue me if my software kills your hamster), but contributers have to adhere to the Apache 2.0 license, which includes a patent grant.
